Be it known that we, HENRY RAINEs and BENJAMIN F. GoooH, citizens of theUnited States, residing at Mason, in the county of Mason, State ofTexas, have invented certain new and useful Improvements inCanopy-Supports; and we do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to canopy-supports for use in supportinginsect-nets over beds, tables, Sac., and has for its object to provide asupport which will be simple and cheap of .manufacture, which may beadjusted to different sizes, and which may be taken apart and packed insmall space when not in use.

In the drawings forming a portion of this specification, and 1n whichlike numerals of reference indicate slmilar parts in the severai views,Figure 1 is a perspective view of Fig. 2 is a section on line 2 2 ofFig. 1. Fig. 3 is a perspective View of a modified form of theinvention. Fig. 4 is a Fig. 5 is a section on line 5 of Fig. 3. Fig. 6is a perspective view of a second modified form of the in- Fig. 7 is atop plan view of a form of the invention which combines two of the otherforms.

Referring now to the drawings, and more particularly to Figs. 1 and 2thereof, there is the support.

. shown a canopy-support comprising extensible uprights 7, which arearranged at the corners of a rectangle, each support comprising a hollowlower portion 8, having a rod 9 slidably engaged therein and providedwith a setscrew 10, by means of which the rod may be held projected atdifferent distances from the upper end of the portion 7. Engaged withthe upper ends of the rods 9 are clamps 11.l having triangularlongitudinal openings 12 therethrough, in one angle of which the rod 9is disposed, the remaining angles being occupied by thedownwardly-turned ends 13 and 14 of extensible side and end rods 15 and16, which connect the several clamps, lthe ends 13 and 14 and the rods 9being held in the position just described by set-screws 17, whichlother.

are engaged with threaded passage 18, communicating with the openings12, and which impinge against the rods 9, forcing the latter between thedownwardly -turned ends 13 and 14. The telescoping side and end rods 15and 16 each consist of supplemental rods 19 and 20, the inner ends ofwhich extend beyond each other and are engaged in triangular openings 21in clamping-collars 22, and with these triangular openings are alsoengagedthe laterally-turned ends 23 of upwardly-eXtendingyolzes 24 and25, which support the central portion of the mosquito-net disposed uponthe support. The collars 22 are provided with set-screws 26, which aredisposed to impinge against the laterallyturned ends 23 and forcethembetween the rods 19 and 2O to clamp the ends and the two rodsagainst movement with respect to each It willthus be seen that thecanopy is extensible both laterally and longitudinally, it beingunderstood that the supporting-yokes 24 and 25 are extensible, as shown,and that the uprights 7 are adjustable vertically to raise and lower theentire supporting-framework.. It will also be seen that the severalportions of the support may be disconnected for packing.

Figs. 3, 4, and 5 illustrate a modified form of the invention in whichthe rods 9 are provided with cylindrical heads 27, which have centrallongitudinal passages 28 with which the upper ends of the rods areengaged,.the rods projecting slightly above the upper faces of the headsand the heads being rigidly secured to the rods in any suitable manner.In the upper faces of each of the heads are a pair of slots 29 and 30,which extend at right angles to each other and which have longitudinalpassages 31 extending downwardly into the head at their inner ends.Between the slots ,29 and 30 is a third slot 32, which also com- IOO inthese slots, and the side rods 15 are similarly disposed in the slots 30and the passages 31 at their ends. In this way the rectangular frameworkis formed. Diagonal crossbraces 33 and 34 are provided which arearranged for longitudinal extension or contraction, as shown, and thesebraces are provided with downwardly-turned ends 35 and are engaged withthe slots 32 in the diagonally opposite heads 27, as shown. To preventdisengagement of the rods and braces from the heads 27, each of theheads is provided with a plate 36, which is centrally pivoted upon theupper end of the rod 9, which extends above the head, and these platesare provided with radial notches 37, which may be brought intoregistration with the slots 29, 30, and 32 to permit of engagement ofthe ends of the rods and braces therewith and may then be moved out ofregistration with the slots to hold the rods and braces in position, asmentioned above. In this form of the invention the rods 15 and 16 andthe braces 33 and 34 each include supplemental rods 38 and 39, the innerends of which are overlapped and are bent laterally around each other inthe form of eyes 40, so that longitudinal adjustment of the rods andbraces is possible.

In Fig. 6 of the drawings there is shown still another modification inwhich the supportinguprights are formed by turning the ends of theextensible side rods 15 downwardly, as shown at 41, and these portions41 are provided with laterally-extending alining convolutions 42, withwhich are engaged the downwardly-turned ends 13 of the ends rods 16,which are thus adjustable vertically, there being suiiicient frictionbetween the convolutions 42 and the ends 13 to preven't downwardmovement of the rod 16 under the weight of the mosquito-netting. Thelower ends of the portions 41 are connected by brace-rods 43, which havetheir ends bent into the form of eyes 44, which encircle the portions 4land permit of pivotal lnovement thereof with respect to the rods 43. Inthis construction the support may be collapsed when desired by pressing'the diagonally opposite corners thereofl toward each other, there beingsufficient pivotal movement between the parts to permit of thisoperation.

As shown in the different views, the supporting-rods 7 may be providedat their lower ends with hooks 45 for engagement with the rails of abed, with bases 46, which may rest upon the floor, or with points 47 forengagement with the ground when the support is used out of doors.

In practice modifications of the specific construction shown may be madeand any suitable materials and proportions may be used for the variousparts without departing from the spirit of the invention.

What is claimed is- 1. A canopy -support comprising corneruprightshaving heads upon their upper ends, said heads having slots in theirupper faces opening at one end through their peripheries and also havinglongitudinal passages communicating with the inner ends of the slots,side and end pieces having downwardly -turned ends disposed in thelongitudinal passages and lying with their portions adjacent to the endsin the slots, plates pivoted to the upper faces of the heads, said sideand end pieces comprising two overlapping rods, a clamping-collar havinga triangular passage therethrough with which the overlapping portions ofthe rods are engaged, said collar havinga thread ed openingcommunicating with one of the angles of its passage, rods disposed withtheir ends in the triangular passages and thumb-screws engaged in thethreaded openings and arranged for operation to bear against the ends ofthe last-named rods to force said rods between the overlapping ends ofthe side and end rods and to force the latter Vagainst the ends of thepassages to prevent movement of the several parts with respect to eachother.

2. A canopy-support comprising corneruprights, extensibleside and endpieces removably connected at their ends to the upper ends of theuprights, each of said side and end pieces comprising two rodsoverlapping at their inner ends, a clamping-collar having a triangularpassage therethrough with which the overlapping ends are engaged, saidcollar having a threaded opening communicating with one of the angles ofthe passage, canopy-supporting yokes disposed with their ends in thetriangular passages ofthe collars,and thumb-screws engaged with thethreaded openings of the collars and arranged for operation to bearagainst the ends of the yokes to force said ends between the overlappingends of the rods and to force the latter into the angles of the passagesand against the sides thereof to prevent movement of the several partswith respect to each other.

3. A canopy-support comprising corneruprights having heads upon theirupper ends, said heads having slots in their upper faces communicatingat one end with their peripheries and having also longitudinal passagescommunicating with the inner ends of the slots, side and end pieceshaving downwardly-turned ends disposed with said ends in thelongitudinal passages and lying with their portions adjacent to saidends in the slots, and plates pivoted to the upper faces of the headsand having notches therein, said plates being movable to bring theirnotches into and out of registration with the slots.

4. A canopy-support comprising corneruprights, side pieces secured attheir ends to the uprights, end pieces connected at their ends with theuprights and each including two rods IOO IIO

IO eration to hear against the last-named rods and to force the latterbetween the overlapping rods tofelarnp the latter in the angles of thepassages.

In testimony whereof we allix our signatures in presence of twowitnesses.
